Türkiye's National Intelligence Organization (MIT) has dismantled a cybercrime network accused of testing stolen credit card information through automated systems, leading to the detention of three suspects in coordinated operations in Istanbul and Kocaeli, northwestern Türkiye.
The operation was carried out jointly by MIT, the Cybersecurity Directorate (SGB), the Gendarmerie General Command (JGK) and the Financial Crimes Investigation Board (MASAK) following a multi-agency investigation into suspicious activity affecting large numbers of citizens.
The investigation began after authorities detected a surge in SMS notifications sent to credit card holders during the night of June 7 and continuing into the early hours of the following morning.
The messages informed recipients of attempted high-value transactions and included one-time verification codes, prompting concerns that card information was being tested without authorization.
After assessing the incident as an organized cybercrime operation, MIT coordinated a comprehensive response involving intelligence gathering, technical analysis, financial investigations and law enforcement measures.
